XT/TL-MF is only suitable for mechanically fixed applications.

- The composite foil facing on both sides of XT/TL-MF incorporates an integral vapour control layer, which helps to reduce the risk of condensation. XT/TL-MF is designed to provide high levels of thermal insulation and drylining in one operation, providing the solution of choice in newbuild and renovation. - Key Facts :Insulation & Drylining in one Application - Provides Continuous Vapour Control Layer - Reduced Insulation Thickness - Suitable for a Variety of Wall Types - Cost Effective Solution in Refurbishment and New Build - Thickness: 77.5mm (65mm PIR Insulation+12.5mm Plasterboard)Length: 1200mm - Width: 2400mm - Board coverage: 2.88m2Weight/m2: 10.41kg - Weight: 29.98kg - Density: 134.32kg/m3Thermal conductivity: 0.022 Wm - KThermal resistance: 2.95m2K/WFire resistance: Class 1Edge profile: Plasterboard - Tapered ; PIR - Square Edge - Minimum compressive strength at 10% compression (k - Pa): 140 1) Integral vapour control layer The composite foil facing on XT/TL-MF provides a gas and vapour tight barrier, reducing the condensation risk.

A continuous vapour control layer is created when the XT/TL-MF joints are sealed and taped in accordance with drylining good practice.2) Fire Stops - An important factor when drylining a wall is to provide fire stops along the top and bottom of each board and around all openings (doors, windows, etc). These are provided by the battens and prevent fire penetrating behind the insulation layer. This also helps to prevent thermal looping, leading to an overall improved U-Value for the wall element.3)Service Void The void created between the timber battens can be used for accommodating services.

- General: Xtratherm XT/TL Thermal Liner is for use as an insulating dry lining system for solid or cavity masonry walls andhorizontal or sloped timber roofs of existing and new dwellings, or buildings of a similar nature. It should be installed inaccordance with the Certificate holder"s instructions - Installation Guidelines:1)Ensure the wall is dry, clean and free of protrusions. Any existing wallpaper should be removed.2)Fix metal frame system/timber battens to the wall in accordance with the manufacturer"s instructions.

Sections should be placed around all wall edges and around openings and services.3)Fix the metal frame system/vertical timber battens at a maximum of 600mm centres (incorporating a vertical DPC behind timber battens). Ensure framing system/battens are wide enough to offer 20mm support to all four edges of the plasterboard. Pack battens if necessary to level the wall.

Extra noggins may be required when the XT/TL-MF is unsupported by the battens.4)Lift the XT/TL-MF into position using wedges on the floor. Insulation should be cut back to accommodate an adjoining panel at external corners. Joints should be tightly butted.5)Fix XT/TL-MF to the frame at 300mm centres using appropriate fixings eg.

drywall screws, at least 12mm in from the board edge. The fixings should penetrate at least 25mm into the timber batten. Fixings should be thermally broken where possible.

6)Seal and tape the joints of XT/TL-MF to ensure a continuous vapour control layer is created. Fill any gaps with foam filler.7)Plaster skim to finish. - Specification Clause:The insulated drylining wall insulation shall be Xtratherm Thin-R XT/TL-MF manufactured to EN 13950 by Xtratherm, comprising a rigid Polyisocyanurate (PIR) core between composite foil facings.

- The XT/TL-MF_ _ _mm with Agrément certified Lambda value of 0.022 W/m - K (PIR only), bonded to 12.5mm plasterboard, to achieve a U-Value of_ _ _ W/m2 K for the wall element. The insulated drylining plasterboard XT/TL-MF shall be mechanically fixed to battens, or proprietary system in accordance with instructions issued by Xtratherm. Refer to NBS clause K10 205, K10 15, K10 245Handling, Cutting and Storage:Xtratherm insulation should be stored off the ground, on a clean flat surface and must be stored under cover.

The polythene wrapping is not considered adequate protection for outside exposure. Care should be taken to protect the insulation in storage and during the build process. - The insulation boards can be readily cut using a sharp knife or fine toothed saw.

Ensure tight fitting of the insulation boards to achieve continuity of insulation as asked for within the ACDs. Appropriate PPE should be worn when handling insulation. The boards are wrapped in polythene packs and each pack is labelled with details of grade/type, size and number of pieces per pack.

Durability:Xtratherm products are stable, rot proof and will remain effective for the life span of the building, dependent on specification and installa
